May be I do not understand how it is implemented in winhttp library. The bypass list * means all from what I understand. Which mean do not use the proxy ("Passes requests to the proxy unless a proxy bypass list is supplied and the name to be resolved bypasses the proxy."). If that is the case how do I accomplish that in Poco?Thanks,MarcM

I guess the proper question would be if there is a way like the wininet call to get the proxy to establish trusted connection without having the explicitly pass them in. As I could not find a way to obtain proxy username and password automatically.
